Super Mini DIPIPM Ver.6 Series
... The Ver.6 Series employs a trimming circuit to compensate the characteristics of the short-circuit protection function embedded in the LVIC. As a result, the variance in the detected voltage for short-circuit protection has been reduced from the conventional ±10% to ±5%. This improved accuracy allow ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
